Phyllidiella rosans? from Indian Ocean [1]

Dear Bill,
To accompany my other message Here are some photos of the other most common nudibranch of Reunion and Mauritius. I saw these phyllidiids in large numbers in all sites I dived. Under the water, they seem quite different than those I sent separately which were always larger. Is this species Phyllidiella rosans?

Dear Marina,
Thanks for these photos. The upper and lower right photos are the form of Phyllidiella rosans in which the tubercles are arranged in longitudinal ridges. I am not so sure about the lower left photo. I suspect that is a form of P. zeylanica.
Best wishes,
Bill Rudman
